Array looping in JavaScript involves iterating through each element of an array to perform a specific action, like processing, modifying, or extracting information.

0 1 2 3 4 5 6 7 8 9

number of numbers


for (let number of numbers) {
  console.log(number);
}

loop through an array


let numbers = [5, 10, 15, 20, 25, 30, 35, 40, 45, 50];
for (let i = 0; i < numbers.length; i += 1) {
  console.log(numbers[i]);
}

loop through an array backwards


let numbers = [5, 10, 15, 20, 25, 30, 35, 40, 45, 50];
for (let i = numbers.length - 1; i >= 0; i -= 1) {
  console.log(numbers[i]);
}
